Specification of Letters Patent.

Patented June 27, 1916.

Application filed September 9, 1914. Serial No. 860,859.

Members for Guns, of which the following is a specification.

The subject matter of the present invention resides in an anchorage member for guns, intended principally for very hard ground, such as rocks, etc.

Two embodiments of the invention are illustrated in the drawing and Figure 1 shows a side elevation, partly in section of a trail end with the anchorage member; Fig. 2, a front view, partly in section of a trail end with bed plate and two anchorage members, constituting a second embodiment; and Fig. 3 is a top plan view of Fig. :2, partly in section.

The embodiment shown in Fig. 1 will first be described. The rear end of the trail sides Aare inclosed by a shoe B. In this shoe is securely fastened a sleeve C in such a manner, that its bore runs perpendicular to the ground surface of the trail end. The sleeve C is intended to receive a spike D, which can turn and slide in the sleeve. The spike D has an edged point Z1 at its lower end; its upper end being provided with a square portion (Z2 on which a handle E may be placed. Vhen to be anchored, the trailend is first placed on the ground and the spike D, after being placed in the sleeve C is driven into the ground by hammer blows. If the ground is very hard, vthe spike D will be drilled into the ground by alternately hammering on it and turning it by means of the handle E.

In the arrangement illustrated in Figs. 2 and 3, the trail end A is slidably connected with the bed plate F. For securing the bed plate on the ground, two spikes are provided, revolubly and slidably mounted in sleeves Gr, which are fastened at the ends of the bed plate, the spikes likewise having each an edged point Z1 and a square portion Z2 for receiving a handle E. In this case, however, the spikes are each provided with a collar d3, whereon the bed plate is supported independent of the ground. These collars have the advantage, that they give Copies of this patent may be obtained for ve cent s each, by addressing the Commissioner o! Patents. Washington, D. C.

`rigid support to the bed plate even if the ground is uneven.

Claims prising a spike with a sharp point having a mill-stone-piercer like action and a bearing for the spike in the portion of the gun carriage to be anchored, said bearing permitting turning of the spike as well as axial displacement thereof along its longitudinal axis.

2. An anchorage device for guns, comprising a spike with a sharp point having a mill-stone-piercer like action and a bearing for the spike in the portion of the gun carriage to be anchored, said bearing permitting turning of the spike as well as axial displacement thereof along its longitudinal axis, the point of the spike extending below the under surfacelof said portion of the gun carriage.

3. An anchorage device for guns, com-V prising a spike with a sharp point having a mill-stone-piercer like action and a bearing for the spike in the portion of the gun carriage to be anchored, said bearing permitting turning of the spike as well as axial displacement thereof along its longitudinal axis, the upper end of said spike being provided with a handle for turning it when being driven into the ground.

4l. An anchorage device for guns having a bed plate and interengaging members on the trail end and on said bed plate permitting training of the trail end on said bed plate, said anchorage comprising spikes with a sharp point having a mill-stonepiercer like action and bearings for said spikes in said bed plate, said bearings permitting turning of the spikes as well as axial displacement thereof along their longitudinal axes, the point of the spikes extending below the under surface of said bed plate; said spikes having a collar on which said bed plate isadapted to rest.

The foregoing specification signed at Barmen, Germany, this 19th day of August, 1914.
